Patent EP-0391782-A1 (EP)
Inventor: TOUPIN JOSEPH FRANCOIS
IPC: G01N25/04
Filed: 1990-04-02
Abstract: The device comprises a first movable part (5) in a closed chamber (4) containing a material which melts at the threshold temperature, and a second movable part (8) outside the chamber. In the "ARMED" state the two parts exert forces on each other which tend to displace them, but the first part is impeded by the solidified material and the second is immobilised by the conjunction of the shapes (12,13) in the casing (9). The melting of the material frees the first part, whose displacement frees the second part which then activates a means of alarm (18). This displacement gives rise to the return of the first part into its initial position, which permits re-arming when the material is again solidified. …<IMAGE>…

Abstract: The invention relates to a ventilator in which the inspiratory gas flow is controlled by the expiratory gas flow. In order to avoid triggering problems, especially when ventilating newborn babies, the ventilator is controlled such that gas flows at a continuous rate through the inspiration and expiration lines. At the same time, the gas flow is measured in the expiration line via a gas flow sensor. According to the invention, the measured signal is used for the control of a valve in the inspiration line such that a constant gas flow is maintained in the expiration line. <IMAGE>
